A Carver police officer yesterday removed his gun and dove into the water to save a drowning chihuahua who was stuck in a submerged truck.

Police arrived at South Meadow Village in Carver about 3:40 p.m. and found a Toyota Tacoma under 8 feet of water, according to authorities. The truck’s owner — Debra Titus of Plymouth — was on shore “completely frantic” and told officers that one of her dogs, Moochie, was still stuck in the truck, according to David Herriman, the officer who saved the soaked pooch.

“We showed up at the water and saw the vehicle was submerged. We were told a dog was still in it so I did what I felt I should do — go in and get the dog,” he said. “It definitely wasn’t easy. I was able to get the door open and then go through some items in the back until I was able to find the dog.”

Titus’ other dog, Stitch, was able to get out on its own.

When Herriman reached Moochie, the dog was unconscious. He then gave the dog “a little squeeze” and it came to.

“Once I got him out of the water, he was breathing,” Herriman said. “I was getting air and he was getting air.”

Herriman, soaked head to toe, had to dry off and get back to work.

“I just handed the dog off and left. I had to go home to get a dry pair of clothes. I drove off into the sunset,” Herriman said, with a laugh. “We only had a few officers, so I had to get back to work.”

Herriman, known by co-workers as a “dog lover,” has an English bulldog of his own and said he would hope someone would do the same for him in the same situation.

He later returned to the scene to make sure the dog was all right.

“An hour later, when I went back to the scene, he looked like a little fluff ball,” he said. “We’d all do it. I know it’s something that’s important to us.”
